Document Summary

2 branches we are interested in (right and left recurrent nerve) Left recurrent nerve is longer (goes down into the chest) Recurrent nerve innervates all intrinsic muscles of the larynx except the cricothyroid muscle (sln) Allows your to cough, clear your throat, pressurize the chest for lifting. Origin, insertion, what they do (adduct, abduct, length change or stiffness change of lamina propria) Just be able to categorize into whether they are elevators or. When you have to pressurize the chest the closure is very high so it resists airflow. Laryngeal airway resistance is high for loud voice, high pitch and less for breathy and low pitch. Slide 4: superior view of the larynx! Identify vocal fold (pearly white if they are healthy) Vocalis and cricothyroid determines thicker vs. thinner. Space between the vocal folds (not a structure) False folds above true and space between the two (ventricular) filled with mucus.
